From a dual-resonance model with currents included through the minimal gauge interaction, the deep-inelastic electron scattering is considered. It gives the Bjorken scaling for νW2 while W1 vanishes, a property which is common among the models where the current is coupled to bosons. Scaling occurs because of the existence of a current-algebra fixed pole. Deep-inelastic electron scattering with one detected final-state particle is also considered which, following Mueller, is connected with the discontinuity of a six-point amplitude. In a special kinematic region, three out of four structure functions scale because of a fixed pole, while outside this region the fixed pole cannot be responsible for scaling anymore. Then a speculation of Pomeranchukon assignment does show the scaling. Inelastic Compton scattering is also considered which, in the parton model of Bjorken and Paschos, scales and is proportional to νW2. This property is satisfied in the present model. Electron-positron annihilation into hadrons is considered without renormalization whose cross section falls off as s-52. It is suggested that a proper dual renormalization for the self-mass diagram of the photon may change this result.
